"The Universe is under no obligation to make sense to you"
Well done on parroting NGT...
Funny thing is if you actually believe this, it requires a leap of faith. Agnostic here, so I have no dog in the fight.
A proper agnostic should have many dogs in the fight that equally and oppositely cancel each other out.
Just a joke lol, for anyone not able to read that through the text alone.
Faith to believe what? I think he mostly just talked about how we DONT know things. A good scientist only concludes things to a certain degree of certainty, so no faith required.
Agreed, my sentiments exactly, destined to seem silly Im sure.
No, it requires evidence, of which we have none. So no agnostic, which is just a poor word for 'atheist', would or should "believe" one or the other. I can say, "X makes the most sense given the data, but I could be wrong." And given the data, I think eternal energy makes more sense. But, you see, I could be wrong. That's the difference in religious faith and rational thought.
There are really only 2 options here. Either something came from nothing, or something was always there. Always being a poor term here due to time coming into existence at the big bang but... I mean always as in no real beginning, something always preceding whatever was there in an infinite loop. Either way, I honestly couldn't tell you which of the two possibilities I find the least baffling! :P
Right???
What if its not an infinite loop though? What if it has just been an infinite linear existence. I don't think our minds can comprehend an existence that either didn't have a start or isn't a loop, but that doesn't mean it's not linear. Honestly, no matter what the explanation is, it's positively mind blowing.
@@mtbjason4 I once heard the phrase “We are limited by our understanding. That applies here me thinks.
I'm sure this isn't an original idea, but it seems like we can take some hints from the idea of infinity. Like, infinity seems to have built into it this idea of something that keeps going or growing, or like how a Set of all Sets eternally grows to contain itself. It just seems to me that if reality is a physical instantiation of infinity, then some type of eternal, outward acceleration makes sense as a fundamental starting point. And those bubbles of outward acceleration can either be gathered up into singularities or they can be the singularities themselves or a combination of both, where a singularity forms and then a bubble of outward acceleration appears around it and pulls it open. I don't know, that last one seems a bit precarious, like what's stopping a bubble of acceleration appearing around us right now and tearing things apart? It seems like there would need to be a safe space where a universe could evolve. Okay, physics dudes, rain on my parade.
Needs revision post JWebb Telescope images. But it just gets more unfathomable. Are finite minds cant contain its grandness.
Whats this? A clip of a clip?
“Lex clips of clips”
Nothing can happen before time begins. So nothing could cause time to begin.
Therefore time doesn’t exist?
@@birhanuashagrie4009 lol
@@birhanuashagrie4009 Or time has always existed.
Yeah but what is “nothing”?
NO ONE KNOWS
“Yet” 😅
@@moro4uYou're avatar is a McDonald's arch..
@@michaelryan2925your

@@riveteye93 who?
Is it even answerable? Any reason we give can just be responded with "why did that happen?". The universe existing seems to defy all logic
When he says we can only consult the universe, it makes me think that truly knowing what was before the Big Bang is forever out of our grasp, like how different universes are uncontactable islands, we know there’s one way systems in reality, for example if you go into a black hole you’ll never be able to observe the universe again, of course there’s the law of conservation of information we could bring in, so maybe that gives us some hope, but again if that information is only the set of information within that universe then how could we ever know that of which is ‘outside’
Science has always verified theories through observation, this is one case like black holes where observation is actually forbidden. If there’s some way the maths of theoretical physics can ‘prove itself’ then we may have hope, but I know that there’s many different mathematical models oof the universe which work for what we see and so deciding on one may be impossible without the observation of their predictions of what was ‘before’. It’s like how the multiverse is considered unscientific.
EVERYONE ALREADY KNOWS!
Only time will tell.
Good song!
There seems to be a fundamental correlation between emergence and time. Consciousness seems to be a candidate for an ‘emergent thing’. And like time emergent things seem to disobey the law of conservation. So state, STATE, is both real, here, now, and disappears as far as we know, from our universe. Arises with time and in as much could possibly possess some of the properties of time. Bending and warping, slowing down, speeding up?
Stuff CAN'T come from nothing....I mean, seriously, how does stuff come from nothing?
A lot of stuff ! Magic
Something coming from nothing has never been observed so it's not even scientific.
It just dose now move along about you’re business
Read a book or 20 books on Quantum Physics
@@scottsound4711 rude...
When Chuck Norris wakes up, we will cease to exist.
Genius!!😂
because the past does not cause the future, the past and the future are simultaneously caused by the laws of physics.
Causality is a type of Ontological Dependence.
Your comment didn't cause my response. It would have existed either way.
@@richardnorton9394 your comment is ontologically dependent on mine in a way mine isn't on yours. to be more precise, causality isn't an illusion- it's a perception. We perceive ontological dependance as temporal causality because of our unique vantage points as conscious observers.
And this reply only exists due to perception and didn't happen due to a preceding cause.
@@richardnorton9394the thing you are perceiving as causality is a type of ontological dependence. Let's call it horizontal ontological dependence. Let's define this axis as being closer/farther from the origin point at the big bang, which is t=0. The ontological dependence that the past and the future have simultaneously let's call vertical ontological dependence. This is the past and the future being simultaneously and instantaneously caused by the laws of physics. The perception of time is the horizontal kind. It's a real thing, but is it causality, or just organization with respect to some axis of similarity? I argue that it's both. The thing we call horizontal ontological dependence, or even temporal causality, it's an axis of similarity in the latent space of all possible structures.
When Chuck Norris wakes up, we will cease to exist.
The BB is a misnomer. Phase transition is better, but even this doesn't capture the idea that events are more and more un-orderable as you approach the big bang (time loses meaning)
I love how they are so confident about things that happened 13.7 billion years ago. Probably going to sound like Copernicus in 100 years. Scientist should have learned this lesson from their predecessors.
Eh? Copernicus proposed that the planets revolved around the sun in the 1500s, when most people believed that Earth was the center of the universe. Some of the details of his theory weren’t right, but he created the foundations that future generations built upon. Science is all about “standing on the shoulders of giants”.
No true scientist ever claims “this theory is absolutely, unequivocally true for now and all time!”. Science is about giving us a high probability of truth based on the evidence we have at this time. The more evidence for something being true, the more likely it is to become the “general consensus”.
All great scientists are humble. Unlike “great” religious leaders, who claim to have all the answers already.
I think folk like you are mixing up the how? with the why?
Science tells us how the world works. It’s done a great job. Look at everything humanity has achieved, it’s astonishing and wondrous.
I’m OK with not knowing “why?”. That’s for philosophy and religion.
Why do people keep *assuming* the universe came from "nothing"? That doesnt make sense. It was in some prior state before the "big bang". It was still something. It was always and will always *be* something.
Nobody knows what was before the singularity, it might not have always existed, and it’s impossible for the universe to be eternal
The big bang assumes its the only one that happens. Its not, black holes and big bangs work together to keep the universe in a consistent recycle state.
Ours is for us. But he’s not saying that. The question wasn’t broad enough. Physicists say there could be an infinite number. Forget black holes have any bearing on a big bang event though. That is woohoo guessing.
Maybe in the traditional models, but no one knows for certain. An interesting take is that presented by Roger Penrose with his "conformal cyclic cosmology". Worth a look at if you've never seen him talk about it before. He's a legit mathematician that got the nobel prize a few years ago for his work on general relativity and black holes, and has a bunch of great books.
Nothing is just a word and imagination of
the 'opposite' of Something,
but Something is the Only Existing Reality.
so, there is No 'nothing'.
Life is Not physical, in it's own Eternal Nature,
The Stuff-side of Life,
is a Genious Camoflaged Empty Space.
What We call 'empty space' is in reality,
'Space-Less Space', because Empty Space
is the Creator, and Space is part of Creation.
Rainbow pictures our Set of Eternal Abilities,
in addition is a Set of Eternal Creator-Principles,
The Life-Desire is the Motor,
Hunger- and Satisfaction-Principles is the Compass.
Something doesn't come from nothing. The answer is they don't know.
Or maybe something does come from nothing. You don’t know. Or maybe there was something at or before the Big Bang. You don’t know.
if it doesn't, where does this something the other sdomething came from, come from?
it's fundamentally unsolvable
There is really only 2 options here. Either something came from nothing, or something was always there. Always being a poor term here due to time coming into existence at the big bang but... I mean always as in no real beginning, something always preceding whatever was there in an infinite loop. Either way, I honestly couldn't tell you which of the two I find the least baffling! :P
Hence the need for something without beginning-infinity. Many have called this infinite thing God.
@@richardnorton9394 circular reasoning/special pleading logical fallacy. why can matter and time not be an emergent property of the universe? It can very much in the same stroke be "something without beginning". I think the only intellectually honest answer is we do NOT know, and we should do our very best to formulate theories and test them and learn more.
we're in the same stage of 2000 years ago when people thought the weather was controlled by a personal god, the only intellectually honest answer at that time was I don't know until further evidence provides itself.
What is the cause of causality? What is the logical explanation of logic? Why is necessity necessary? Who made God? Eventually you must realize that nothing is fundamental. Everything is emergent. If causality exists, then it has no cause. And it has no cause because it simply didn’t always exist. Something DID come from nothing, but only before it was impossible for such a thing to occur. I’ll be awaiting my Nobel prize in the mail.
There’s no such thing as “nothing” because nobody can define it. If there’s no space-time, then what is there? Define the state of nothingness…
"In the beginning God created the heavens and the earth" is starting to sound less like theology and more like science
I bet you Tucker Carlson knows

Beginninglessness is not that hard to conjecture.
And black can be white
My theory is that the Big Bang is a zero point implosion. The singularity within the centre of a black hole is the absolute presence of every frequency of light within the system in its primal state. If all light within a solar system has already been absorbed by the singularity then the rings around the event horizon are the last vestiges of the solar system and the same would be true beyond the event horizon but the polarity reversed (Imagine the infinity symbol). In this scenario both of these polarised vortices will have vacuums that will reach zero point simultaneously resulting in an annihilation event and a system that will endlessly self perpetuate. I imagine the force of a zero point implosion would make quite a big bang creating another 2 parallel polarised realities.
"absolute presence of every frequency of light", what thehell are u talking about? you should stop taking drugs dawg you dont make any sense
My theory: God sneezed
GOD ALMIGHTY
BOOOOYAAAAAH
I'm no church-goer, but I wonder what God's intentions were? Has he left us enough hints to figure that out? Is there eternity? When did it begin? The older I get the more questions I conjure.
God
magical unicorn.
God created the heaven in the Earth don’t be fooled by this nonsense
Nothing can create everything.
People say that God is not real, but yet they believe nothing created everything 🤷🏻♂️
And in your opinion, what created god? Both possibilities are equally baffling.
@@jakubdonovan4985 as a Christian, I too have wondered what created God but then that wonder has been met with the idea that because God is outside of our laws of physics, creationism breaks down (or should, anyway)
@@91wheelz what's outside God then?
I bet even God doesn't really know why he's God to begin with
@@aiya5777 I do not know, I am humble enough to admit that. What I do know is that there is nothing greater than God so if his words are true and he dwells outside of our physical parameters then that tells me that he is timeless and has always been where he is. This topic is too grand for a human mind to comprehend much like trying to picture the distance of 13.8 billion light years
Ha! I love scientists whose position is "I have no idea how or why it happened but I know God definitely didn't do it."
So sciency!
Sean Carroll doesn't understand that Big Bang is just the universe going from being dense to expanding, not that there was nothing before it.
The main problem with Academics is they pretend they know important stuff they don't.
Trump fan Peterson fan pool fan crowder fan. Did I miss any? 😂😂😂😂
@@user-xr7fi6dy1w Yep, the fact that you think you know more than you do. Clearly an Academic.
@@billrentz9133 never been to college chief… nice try though. 👍
he clearly states "we don't know" to things he does not know several times
What absolute nonsense. I hate academia for different reasons., but nowhere does any academic claim to know the questions he COULDN’T ask here, and readily says “we don’t know.”
The more these scientist learn about the big bang - the more they are forced to default to the 'God Theory' ... it's so obvious that the point of singularity came from a higher power
So obvious?
The bible describes many as blind.
Its not so obvious im afraid.
Where did God come from then? At the end of the day something or God literally came from nothing.
Im not religious, but maybe god doesnt have a beginning. Maybe god is, just is. Humans cant explain what this is were experiencing, all we can do is try to 'make sense' of this environment were in. So a creator like a god, doesnt sound that farfetched.@robertweaver4728
Nope, it was a very small hobbit with a magic hat. He pulled the universe out of a hat. I know this because there are hobbits in an old book I read and I saw a guy unexpectedly pull something out of a hat once.
I think if you watch this clip enough times in repeat no matter your beliefs you realize that there is truly a God and you should find him no matter what
Have these guys ever heard of God ?
Have you ever heard of the guy who came up with the idea of the Big Bang? In terms of the expansion observed by Hubble? The dude was a Catholic priest and physicist. Whether or not you want to bring God into this is besides the point. You can't plug "God" into a mathematical model. That's why we do physics and science and talk about religion and philosophy as a "separate" thing sometimes. Some physicists are atheists that don't care for that way of thinking at all. Some others (doing exactly the same kind of work) feel that they are trying to understand the "mind of God" in the sense that Einstein talked about it. Others also believe in a more personal God that is even more involved. None of that changes how we do physics.
@@hajsh67 Ok , so according to physics, how did something emerge from nothing?
0+0=0
0×0=0
0÷0=0
0-0=0
Simple math.
We didnt come from nothing, thats impossible.
The original existence is God.
Cope.
0 divided by 0 is indefined.
Where did God come from?
@@dgreen8388😂😂 funny
You are the only one "coping" dude. Invoking a complex deity just because you don't understand something. If we didn't come from nothing, then explain how a more complex version of us came from nothing. You can't.
@@dgreen8388 God is eternal he doesn’t have a beginning or an end….
Our human brains can’t comprehend that if our brains could comprehend that, then he wouldn’t be worthy of being called God
Let me give an example, Steve Jobs, invented the iPhone…. That doesn’t mean Steve Jobs is running around inside the iPhone, making changes and running apps 🤷 so that means Steve Jobs lived outside of the iPhone and wasn’t limited to it!
God lives outside of our space and time plane that we live on
he is not limited to space and time
like we are…
He lives in a plane of existence where time does not exist, so therefore he doesn’t need to be created because he has always existed
The problem is we want to fit to God flawed human brains…. But we can’t understand God that’s why he’s God…
It’s like when you stand next to a little ant that has no idea you’re there and the ants tiny brain cannot understand the life you live or that you can drive a car…
We are like ants compared to God
God bless you, bro. Have a good night. 🙏🏻😎
Sean Carroll is a fool, there was no big bang….how confused is our idiocracy of science
